Changes For Bug 352
...
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Use newly added API in MRegisterInfo and don't expose the allocatable
...
register set anymore. Its users now use the MRegisterInfo API.

There is no need to store the MBB along with the MI any more, we can now

ask instructions for their parent.

Now that MachineFunction/MachineBasicBlock keep a mapping of blocks to ID #'s
...
use them instead of a local LiveVariables numbering

map.

Instead of building a private numbering of MBB's use brg's nifty auto-numbering.
...
Also convert df_iterator -> df_ext_iterator for subsequent stuff I'm doing.

Patch to fix PR337. Make sure to mark all aliased physical registers as used
...
when we see a read of a register. This is important in cases like:
AL = ...
AH = ...
= AX
The read of AX must make both the AL and AH defs live until the use.

Stop LiveVariables from using BasicBlocks as part of the mapping, instead
...
use MachineBasicBlocks. To do this, we traverse the Machine CFG instead of
the LLVM CFG, which is also *MUCH* more efficient by having fewer levels of
indirections and mappings.

MRegisterInfo::getNumRegs() instead of
MRegisterInfo::FirstVirtualRegister.
Also use MRegisterInfo::is{Physical,Virtual}Register where
appropriate.

Change MachineBasicBlock's vector of MachineInstr pointers into an
...
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.
